Git commit that doesn't override original authors in git blame

Question

I\'ve used a perl script to modify all tab characters in a php git repository and changed them all to 4 spaces.

$ find -iname \\*.php -exec perl -pi -e \"s/\         


        

Answer 1

Thanks to wnoise on git: change styling (whitespace) without changing ownership/blame?, I came up with this to run an arbitrary filter on git history, so using this you could rewrite history to make it look like offending whitespace or other issues were never committed, leaving the original authors in tact but your code cleaned up: git filter-branch --tree-filter 'git diff-tree --name-only --diff-filter=AM -r --no-commit-id $GIT_COMMIT | php cleanup.php' HEAD

Answer 2

It isn't the responsibility of the commit command to decide how to treat whitespaces, but the responsibility of the blame command because it is blame which analyzes the differences between versions to get the author of each line. So searching for an option to ignore whitespace in blame:

The option -w is defined as: "Ignore whitespace when comparing the parent's version and the child's to find where the lines came from." http://kernel.org/pub/software/scm/git/docs/git-blame.html
